When you are attempting to uninstall modules, you must not delete the files via FTP. Dolphin needs the files to be intact in order to perform the un-installation.
1) Firstly, open this file in an editor and remove line 32 :
modules/deano/deanos_tools/install/installer.php
2) Secondly, Re-upload the files you removed.
3) Attempt to do the un-installation from the admin panel again.
4) If the un-installation is successful then you can go ahead and remove the files via FTP.
